Moving to Mexico on Sunday to work at ASF as well, wanted to recommend a book to you all about the city, even though it's only days away. The book is a quick read as it is well written, and has provided us with a lot of insight from the perspective of an expat. The book is called First Stop in the New World by David Lida. The author also has an excellent blog about the city, just google his name, the blog has pictures and a lot of insight. I'll be bringing the book with me, so if you don't happen to have the time to get it and read it by then, you could certainly borrow it! Best of luck and safe travels!
